Cross-border Undercover Policing's "Alphabet Soup": The Accountability Gap in Global Governance

When Undercover Operations Cross National Borders

Established in 2015, the UK Undercover Policing Inquiry (UCPI) was intended to investigate the police's decades-long infiltration of social and political organizations. Yet its scope was strictly limited to England and Wales. This meant that covert deployments of British officers abroad—such as Mark Kennedy's frequent appearances in Denmark, France, Germany, Iceland, Ireland, Italy, Spain, and even the United States—almost never came within the official inquiry's purview. Mark Kennedy's identity was exposed in 2010, and researchers later found that he was not an isolated case.

If this were merely a case in one country, the problem might still be absorbed by national mechanisms. But the reality is that behind these undercover operations lies a complex system of transnational coordination. In government documents, parliamentary inquiries, and academic research, strings of acronyms—ARGOS, ESG, SENSEE, SCG, ISLE—have gradually surfaced. Researchers have called them "alphabet soup," referring precisely to the network bodies that exist to coordinate cross-border undercover policing.

From Europe to the World: An Invisible Coordination Network

A Statewatch briefing listed at least six known transnational police coordination entities. The most representative among them is ARGOS (the "Regional Surveillance Alliance"), led by Europol. According to Europol documents, ARGOS was created to "bind together informal regional expert groups," giving every EU member state a voice in the EU's covert surveillance network. It links three major regional networks: the European Surveillance Group (ESG), covering Western and Northern Europe; the South-East European Surveillance Expert Network (SENSEE); and the Surveillance Cooperation Group (SCG).

ARGOS was not merely a paper exercise. In November 2015, the first ARGOS meeting was held at Europol headquarters in The Hague, with all 28 EU member states at the time sending delegates. In April 2018, Austria hosted an ARGOS meeting themed "Covert Surveillance: Future Needs and Solutions," attended by 85 representatives from 32 countries. More and more details indicate that these once-loose exchanges among peers are becoming institutionalized. Europol, together with the chairs of the various networks, has formed a board of directors and plans to convene a joint general assembly every three years.

One Case, Two Black Holes of Transparency

Mark Kennedy's case reveals the essence of how this network operates. In 2012, the German government acknowledged that Kennedy's deployment had been discussed at a 2011 meeting of the "European Cooperation Group on Undercover Activities" (ECG-UA). In other words, transnational networks are not only about exchanging intelligence or training techniques; they also directly discuss infiltration strategies targeting specific social movements. How these meetings decide on targets, how intelligence is shared, and how participating countries authorize operations—all of it is a black hole.Secondly, domestic investigative mechanisms cannot reach these transnational networks. The remit of the UK inquiry only covers England and Wales, so the overseas conduct of British undercover officers is neither subject to UK inquiry jurisdiction nor has it elicited any systematic response from foreign governments. The absence of accountable actors leaves these policing operations effectively operating outside the rule of law. Even if one claims that such cooperation is primarily aimed at serious and organized crime, the UK experience has already shown that the label of "domestic extremism" is enough to turn peaceful protesters into targets for infiltration.

ESG Warnings from a Global Governance Perspective

Viewed through the framework of international development research, transnational secret policing networks are not an isolated phenomenon but part of the global security governance system. Sustainable Development Goal 16 calls for "effective, accountable and inclusive institutions." However, when police coordination networks operate beyond parliamentary oversight and with almost no independent review mechanisms, that goal encounters structural obstacles.

From an ESG perspective, the core of the "G" (governance) lies in clear lines of authority and responsibility, transparent accountability, and the rule of law. Transnational surveillance networks clearly run a deficit in precisely these areas. For investment institutions, international organizations, and non-governmental partners, the cross-border conduct of a country's policing system is directly related to the quality of its domestic governance. If a state can use covert means to infiltrate civil society groups, its governance credibility will inevitably be damaged, and that damage will also spread to the trustworthiness of its international development cooperation.

This matter also carries a warning for the Global South. When many developing countries receive police training, equipment, and technical assistance, they often need to sign horizontal cooperation agreements with European institutions or partners. If such cooperation embeds surveillance networks that lack transparency safeguards, it may fuel domestic suppression of dissent, squeeze civic space, and ultimately undermine development achievements. In international development cooperation, police capacity building and the protection of civil liberties must advance in tandem; otherwise, aid risks becoming an amplifier of external governance deficits.

Transparency Is Not the Opposite of Efficiency

Europol and related networks have always emphasized the importance of coordinating cross-border operations in fighting crime, and that necessity is hard to deny. However, the pursuit of law enforcement efficiency cannot come at the cost of systematically evading democratic accountability. As the Statewatch briefing points out, through freedom of information requests and parliamentary questions, researchers have been able to piece together the outlines of these networks. But those channels remain limited: external bodies find it very difficult to learn about the specific decisions made at ARGOS meetings, let alone to subject a specific undercover operation to judicial review.

The new joint oversight group of the European Parliament has provided a certain channel of supervision over Europol, but it faces a complex network that is multilayered and extends beyond EU member states. At that ARGOS meeting held in Austria, not all of the 32 participating countries were EU members, nor were all of them subject to the jurisdiction of the European Parliament. Clearly, relying solely on EU institutions cannot close the accountability gap.The long-term perspective of global development research reminds us that any secretive power institution, if it lacks external checks and balances, will ultimately erode social trust. If citizens may be monitored by foreign secret police during peaceful assemblies, while their own police are not even accountable for such conduct, then the term “rule of law” loses its meaning.

Conclusion: Making the “Alphabet Soup” Traceable

Untangling the alphabet soup is not merely about reconstructing a certain chapter of undercover history; it is about ensuring that future cross-border law enforcement cooperation is built on full respect for human rights and a clear democratic mandate. Before moving into multilateral law enforcement networks, all countries should define in advance their boundaries of authority and oversight mechanisms.

International development agencies, human rights organizations, and academic researchers should continue to push for transparency reviews of the security sector and for incorporating police cooperation into the global governance assessment framework. It is not enough to ask what the police have done abroad; what is needed is a system that enables citizens to know the boundaries, file complaints, and correct deviations. Otherwise, sustainable governance remains merely words on paper.
